Transient elastohydrodynamic squeeze film interaction

Model ID: 14109

This benchmark model computes the transient pressure distribution and film height in a squeeze film bearing for lubrication in a nonconformal conjunction of a solid sphere
and an elastic wall separated by a lubricant film.

This model solves the benchmark case of hydrodynamic interaction between a solid sphere and a wall separated by a lubricant film, and extends the benchmark case to
include elastic deformation and stresses on the contacting wall. The model set up involves a solid sphere being pushed by an external force towards a solid plane wall. The lubricant layer gets squeezed by the approaching ball and leads to rise in pressure in the lubricant. The calculated maximum lubricant pressure and change in film height
with time are compared with analytical solutions.
